高寒地区水工混凝土建筑物表面预防护技术应用探讨

Discussion on Applying Surface Pre-protection Technology of Hydraulic Concrete Buildings in Alpine Region

本文以高寒区水工混凝土结构为背景,总结了混凝土结构多种缺陷的防护措施和防护材料的选取原则,重点分析了北方高寒地区水工混凝土建筑物缺陷类型和产生的原因,提出了水工混凝土结构预防护理念,通过单参数数值模拟计算验证了水工混凝土建筑物预防护的重要性和可行性,可为高寒地区水工混凝土建筑物耐久性设计、施工等提供指导和借鉴。

In the paper, the hydraulic concrete structure in alpine regions is regarded as the background. Protection measures and protection material selection principles aiming at many defects in the concrete structure are summarized. Defect types and reasons of hydraulic concrete buildings in North are mainly analyzed. Pre-proteetion concept of hydraulic concrete structures is proposed. The importance and feasibility of hydraulic concrete building Pre-protection are validated through single-parameter numerical simulation calculation, thereby providing guidance and reference for durability design, construction, etc. of hydraulic concrete buildings in alpine regions.
